Hi,
The following vulnerability was published for abseil.
CVE-2025-0838[0]:
| There exists a heap buffer overflow vulnerable in Abseil-cpp. The
| sized constructors, reserve(), and rehash() methods of
| absl::{flat,node}hash{set,map} did not impose an upper bound on
| their size argument. As a result, it was possible for a caller to
| pass a very large size that would cause an integer overflow when
| computing the size of the container's backing store, and a
| subsequent out-of-bounds memory write. Subsequent accesses to the
| container might also access out-of-bounds memory. We recommend
| upgrading past commit 5a0e2cb5e3958dd90bb8569a2766622cb74d90c1
